I was wondering if it was possible to hit the rev limiter in 6th gear, has anybody hit 5 & 6th gear limiter?

 

:/

put your car in 5th or 6th, put your foot on the clutch, and put the pedal to the metal, and you will hit the rev limiter in '5th' or '6th' gear.

 

Try it out.

 

You might be able to in 5th but it wouldn't be legal on any roads around here. 6th would be almost impossible unless you were making alot more power. Why do you care?

 

Perfect question for bizzybear...hope he makes a video to show us.







To answer your question, yes in 5th and no in 6th. The Si is speed limited to 133 mph so it won't reach rev limit in 6th.

 

The Si in a racing situation only gets trough 5 gears and 6th is for highway cruising/MPG's.

I saw the video of bizzybear hitting the rev limiter in several gears, i got curious to wether if it was possible to hit the rev limiter in 5 and 6 because its not legal on the roads. I know that it might be possible in 5th and a i got a little curious about 6th, wether it will hit the rev limiter and top out or top out before that

 

I'm gonna reply to a couple of people that replied to this thread.

1st: I don't understand why people say "Aaa, it's illegal to hit those speeds anyway on a public road" For the most part it seems like little racecar drivers are the only ones that drive four banger hondas. Proof is all the civics with fart pipes on their cars including mine. I see old CRX's and civics with wheels and exhausts trying to race people all the time. So yes people take their cars to 130 mph all the time. So to the guy that said why do you car must be a wuss....What do you mean why do you care?...Give the guy a break he wants to know how fast our cars go.

2nd: The guy that said in a racing situation you only get through 5 gears and 6th is for highway cruising? 5th and 6th are pretty tight to me. You lose a whole 1000rpms when you shift from 5th to 6th. Look at my chart below. 70mph at 3000rpms is not exactly cruising, as evidence of the poor 29mpg highway that are cars get. These are SI's...fuel economy was a little lower on the list my friend.

No my "FRIEND" 6th gear is for MPG's and if you had any common sense you would realize it.

Cruise on the freeway at 65 not 70 and your still at 3k. Just because the gear dont go to 2k or the "Desired RPM Range" for better MPG's does not mean 6th gear is for racing. The reality is that in 6th gear your not really gonna go anywhere since you pretty much max in 5th gear.

Besides just because the car is an SI doesnt mean people dont car about MPG's. Just because its an SI doesnt mean that people dont want to get all the desired MPG's out of the car.

I bought a MS3 which gets crap MPG's but that doesnt mean im gonna take off like a bat out of hell every light and floor every gear to lower my already bad MPG's.

:edit: Yes driving at 3k in this car is considered cruising. K Thanks Bye

 

I love the people that claim they can cruise around at 1200rpms

 

I believe that if the car sat at say 4200 at 70mph like a Type R or similarly gear car it would actually get better gas mileage than at 3000 at 70mph. You would require less throttle input with the higher RPM to reach your desired speed/change therefor reducing the amount of gas your car consumed.

Just a thought... I may be wrong though?

 

cruising implies you are already at the desired speed, hence "cruising altitude" in a plane, so you wouldnt be changing very much any way. unless you want to pass quickly, in which case you should downshift. also how would a 40% higher RPM increase gas milage? wouldn't that just use 40% more fuel?

 

the si is not speed limited....i have personally had my car to 157mph racing a c5 vette.

 

OP:

It has been said already but I want to clarify, because some false and confusing information has been posted;

The following refers to a stock Si:

You can hit the rev limiter in 5th gear, but you cannot high the rev limiter in 6th gear. Gearing and/or top speed governor do not allow the car to accelerate into the higher rpm range of 6th gear, which is a highway (or overdrive) gear, intended for use on the highway to achieve optimal MPG. This is a fact and cannot be disputed, either by charts of what the car could potentially do, or by someone else's "personal experience".

Anyone who drives sensibly on a decently long (50 miles or more) highway trip, will achieve better than 29 mpg. I regularly get 34 mpg on 200 mile trips (100 miles each way) to and from my GF's college, and that is with a few highway runs here and there.

***My car (2008 Si) has a top speed limiter of 133-134 mph, depending on how my car feels at the time. I've read, but never personally experienced that 2006 SIs did not have a top speed limiter, but were only limited by the gearing of the transmission. I've also read that Vtec will not activate in 6th gear (and that would make sense since it does not need it), but again, I've never personally experienced that, as my car limits my speed well below 5800.**

 

Do you have an '06?

A few possibilities:
1)It wasn't even a "race", because an Si cannot keep up with a C5.
2)Your car isn't stock.
3)You're full of doo doo

 

Considering peak torque is so HIGH in the RPM range cruising at a lower RPM may be detrimental to fuel economy because you are lugging the engine thus requiring more tps angle.

What a whopper!

What model year is your vehicle? Some very early production 07 Si sedans weren't speed limited because I had one of the 1st few 07 Si Sedans to roll off the assemply line.

To be able to do 157 you must have had forced induction, nitrous or been driving down an 8% grade with 70mph wind behind you.

 

ohhh really lets see a video or sumthin myne is a 07 all i can go upto is 134

 

... or a Hondata reflash?

 

Sorry Hondata reflash doesnt eliminate the speed limiter.

 

Go ahead and set your cruise control in Pittsburgh and in mountainous areas and you will not get your 34 mpg's. Sure go on the flat roads and you might get 40.

Also my car hits vtec in 6th gear and I'm not sure it's because of the Hondata reflash, but I cannot confirm it didn't before since I turboed the car early and don't remember.

And what do you mean it doesn't need vtec in 6th gear? If I'm going fast in 6th gear, 100mph plus and I want to go even faster with out shifting.....Then I guess I need it...speak for yourself!

 

Wow dude are you that inept at reading? Of course it's because you have the reflash the crossover point is significantly lower than stock.


Your Hondata Reflashed car isn't stock, douche

 

Yeah no **** the crossover point is lower.

Are you sure of your info? So let me get this right. A hondata reflash doesn't eliminate the top speed limiter, but it allows the car to engage vtec in 6th gear which is otherwise not possible on a stock car. Why would they change one and not the other? I'm not sure

 

1st... the final drive on these cars is crazy if you would put these engines in a 2300lb car it would probably go 12's. lol

2nd... on the 6th gear issue. Honda can't make a gear that would let the car cruise at 2.5k at 70 because the power would suck. As car savy people.... we understand the benifit of having lower gears but the average consumer wouldn't know and it would probably be an area of complaint for most buyers.

 

Wait, i'm a little confused about people saying there is and there isn't vtec in 6th gear, so is there or is there not vtec in 6th gear?

 

i personally hit 158. in my car.

i do own a hona
i do own a civic.
i do own a k seriousss.
but its all in my 94 sedan, running on hondata
158 at about 6500rpms in 6th with the rev limiter at 9k.
stopped at 158 cuz i was shitting bricks..

just felt like posting.lol

my .02 cents cant apply here with stock si's
lol
